Google building hackers say Australian offices at risk

US security researchers who hacked into one of Google's Australian offices say hundreds of other buildings around the country are vulnerable.

The California-based Cylance security research team revealed earlier this week they had been able to hack into the building management system (BMS) of Google's Sydney Wharf 7 office, allowing them to take over the building's air conditioning.

They say they have found other major Australian buildings, including hospitals, banks and government departments are at risk.

Experts say depending on the configuration, a BMS can control anything from lights through to locks, air conditioning, lifts, fire alarms and even sewerage.
